Most reports here on the 4CS is that they haven't been valved very well at all. Mushy, driving, blowing through the stroke, and bottoming before even getting up to race pace. The good news is that local tuners have sussed out what works and can make them amazing.
Look forward to your comments Trev. I don't even need to mention that I also much prefer the 250 capacity over the 300.
